4.3 Opening levers:
After unscrewing and pulling out the pressure release plug, the lid can be opened. To overcome the friction of opening, use lever (Fig. 2) to push against the lid with a cam action. Be sure they are inserted all the way flat to the housing before turning to avoid damaging the protrusions on the lid. The body has four holes on each corner edges for opening. Gently lever off the lid with the supplied lever (Fig. 3) taking care not to twist the lid excessively. The lid should be opened keeping it approximately paralleled to the body at all times, turn first one corner a little, then the other a little, and repeat again until the lid is opened. Remember to unscrew and pull out the pressure release plug all the way first, otherwise the air pressure will resist attempts at opening. Lay the lid on a flat stable surface after opening.
